TRENTON — Federal prosecutors have issued a new subpoena to the Port Authority seeking records related to claims that Gov. Chris Christie's administration retaliated against Jersey City Mayor Steve Fulop, according to a report by the Wall Street Journal.

The subpoenas call for records from a number of former officials at the agency regarding interactions with Jersey City, the report said, citing an anonymous source. The officials include former Port Authority officials Bill Baroni and David Wildstein, two Christie allies at the center of the George Washington Bridge scandal, according to the report.

"We're not going to comment on subpoenas or investigations," Foye said. "That's the position we've taken all along."

Kevin Roberts, a spokesman for Christie's office, declined to comment.

The subpoenas are part of a wide-ranging investigation by New Jersey U.S. Attorney Paul Fishman into the bridge scandal that has surrounded Christie's office for more than a year. Investigators have been looking into accusations that members of the governor's office and allies at the Port Authority closed lanes at the GWB in September 2013 because the Democratic mayor of Fort Lee decided not to endorse Christie for re-election that year.

Fulop, a potential Democratic candidate for governor in 2017, also declined to endorse Christie, and he has said the governor's administration responded by quickly cancelimg meetings he had scheduled with state commissioners.

The Wall Street Journal report said documents uncovered during the bridge scandal probe contain indications that the administration was retaliating against Fulop.

The paper reported in January that federal prosecutors had subpoenaed Christie's re-election campaign for documents related to canceled meetings with Fulop.
